A Comprehensive Review on the Importance of Different Magnetic Nanoparticles in Nanoburning, Hyperthermia and MRI Devices

Abstract

Magnetic nanoparticles (MNPs) have emerged as a transformative component in modern biomedical science, particularly in diagnostic imaging and therapeutic applications. This review presents a comprehensive analysis of the role of various magnetic nanoparticles in nanoburning, hyperthermia, and magnetic resonance imaging (MRI) devices. Recent advancements in nanotechnology have significantly enhanced the functionality of imaging techniques, enabling precise diagnosis of complex diseases such as cancer, neurological disorders, and cardiovascular conditions. Among these techniques, MRI stands out due to its superior soft tissue contrast and non-invasive nature. The incorporation of MNPs, especially super paramagnetic iron oxide nanoparticles (SPIONs), has further improved MRI sensitivity and specificity through enhanced contrast mechanisms. In therapeutic domains, magnetic hyperthermia has gained considerable attention as an effective cancer treatment strategy, where MNPs generate localized heat under an alternating magnetic field to selectively destroy malignant cells while minimizing damage to healthy tissues. Additionally, nanoburning and magnetically controlled drug delivery systems provide innovative pathways for targeted therapy and controlled drug release. The physicochemical properties of MNPs including size, shape, surface coating, and magnetic behavior, play a crucial role in determining their biomedical efficacy and biocompatibility. Furthermore, this review highlights different types of magnetic nanoparticles such as ferrites, cobalt ferrite, and manganese ferrite, emphasizing their distinct advantages in medical applications. Despite significant progress, challenges related to toxicity, stability, and targeted delivery remain. Future research should focus on optimizing nanoparticle design and integrating multifunctional capabilities to advance clinical translation. Overall, MNPs hold immense potential to revolutionize diagnostic and therapeutic approaches in modern medicine.
